This project is designed to assess the impact of implementing a hemodynamic optimization protocol, utilizing flow guided parameters that is provided by technology from Edwards Lifesciences, for patients undergoing high risk cardiac surgery. Importantly, this project is being targeted as a QI initiative because there is no evaluation of new technology or procedures. All technologies and procedures are currently being used for patients undergoing cardiac surgery. Rather this project is evaluating the implementation of a multi-dispclinary developed protocol that seeks to remove variability in which providers are currently treating patients hemodynamics during and acutely after cardiac surgery. Previous research has demonstrated that implementation of hemodynamic management protocols improves perioperative outcome in surgical patients. This project seeks to evaluate the impact of implementing this protocol as the new clinical standard for high-risk cardiac surgery patients. Specifically, this protocol would be a comprehensive hemodynamic management strategy that would-be initiated in the operating room post-bypass and then continued for the first 12 hours in the intensive care unit (see figure below). To restate, all technologies and procedures are currently being performed for these patients, however, there has not been a protocol guiding how practionioners use this technology. The project is evaluating the impact of protocolized treatment strategies. Importantly this protocol has been designed, reviewed and agreed by the motivation of the physicians who are currently responsible for managing these patients hemodynamics. Since this project does involve alterations in procedures or technologies we are seeking to proceed as a quality improvement project. Additionally the protocol is one that has been reviewed and agreed to provide the optimal management strategy for these patients. This again is the overall focus of this project, to implement a hemodynamic management protocol to improve outcomes in patients undergoing cardiac surgery.
The purpose of this study is to evaluate preoperative objective measurements and operative objective measurements to determine if there is any effect to postoperative outcomes. Patients who were 13 years old or greater at the time of arthroscopic osteocapsular release were followed clinically and radiographically to determine best practice and optimal treatment and technique, risk and rate of complication, and postoperative outcomes.
The purpose of this study is to evaluate reverse total shoulder arthroplasty patients preoperative objective measurements and operative objective measurements to determine if there is any effect to postoperative outcomes. Patients who were 18 years old or greater at the time of surgery were followed clinically and radiographically to determine best practice and optimal treatment and technique, risk and rate of complication, and postoperative outcomes.
The objective of the RHAPSODY study is to evaluate the performance of new software features in subjects undergoing standard of care catheter-based endocardial mapping for atrial or ventricular tachyarrhythmias using a commercial Rhythmia Mapping System. Results from this study will be used to guide development and refinement of new software features that may be implemented in future commercial software releases.
The objective of this study is to determine if a non-invasive technique, using an innovative analysis of electrocardiogram (ECG) data, would allow for detection of respiratory events during sleep and discrimination between central and obstructive apnea. Obstructive Sleep Apnea (OSA) is the most common respiratory disturbance seen during sleep, with an estimated prevalence of 10 % in the population and is strongly associated with the development of cardiovascular disease. In patients with underlying cardiac disease, particularly in heart failure (HF), central respiratory events such as Cheyne-Stokes Respiration (CSR) are often seen during sleep. The presence of CSR is also associated with increased cardiovascular morbidity and mortality. Currently, the identification and classification of sleep related respiratory disturbances is performed during over-night sleep studies (polysomnography), which are labor-intensive, time-consuming, expensive and difficult for patients. Thus, the development of alternative techniques to assist in the identification of those events in the outpatient setting is of marked importance for widespread screening of sleep apnea.
A retrospective analysis of historical data looking at hematological remission and survival in adult relapsed / refractory B-precursor acute lymphoblastic leukemia patients.
New payment methods such as Accountable Care Organization (ACO's) and medical homes facilitate are new models for providers to deliver cost effective, quality patient outcomes. Integrated Care Coaching (ICC) is a healthcare delivery model combining telephonic interventions with an intelligent information technology platform that offered validated protocols and patient outcomes tracking. Health Integrated, Inc. has developed a validated program of Integrated Care Coaching (ICC), which was branded as "VitalCare", and implemented with over 7,000 members of the Scott and White Health Plan in Texas, would reduce healthcare costs/achieve a return on investment (ROI), improve clinical outcomes, and be satisfying for participants.
We plan to analyze the data to meet the primary objective of the study: To characterize the change in bone mineral density (BMD), as measured by lumbar spine DEXA, during and following treatment with tenofovir DF-containing antiretroviral therapy in HIV-infected children. In addition, we plan to analyze the data to meet 2 secondary objectives of the study: 1. To study and monitor markers of bone metabolism - calcium, phosphorus, parathyroid hormone (PTH), vitamin D levels, bone resorption markers (urinary collagen cross-linked N-telopeptide and free deoxypyridinoline), bone formation markers (bone specific alkaline phosphatase and osteocalcin) - in HIV-infected children treated with tenofovir DF-containing antiretroviral therapy. 2. To study immunologic, virologic and clinical effects of tenofovir DF administered to HIV-infected children in combination with other antiretroviral therapies.

For the purposes of this study as a core lab coordinating center, the investigators will be performing P31 MRS core lab analyses; hormone core lab analyses; lipid core lab analyses; glucose, insulin and HOMA core lab analyses; exercise stress test/Holter monitor core lab analyses; brachial artery reactivity test core lab analyses; full study data analyses for manuscript preparation and the writing and submission and publication of manuscript. The main trial duration: December 1999 - May 2003. The ancillary data analysis project duration: April 2006 - March 2010.
The researchers have developed and distributed several software packages for pedigree analysis (FAST, CASPAR, PedHunter, IIC) and cancer genetics (oncotree, METREX). Users who need assistance with the software or who want to see new features added often send the researchers data files that include human data. The information is normally coded, and the researchers do not have access to the identification of the people whose information is in the files. Sometimes the content of the files gives rise to collaborations between the software developers and the providers of the files. Because concerns over the confidentiality of medical information have increased significantly over the past few years, the researchers must apply for exemptions from detailed ethics committee oversight for every data set they receive. This process is cumbersome and makes it difficult to assist software users. The amount of information required to apply for an exemption also poses a barrier to collaborations. A full protocol will subject all data sets to ethics committee oversight without the need for individual exemption requests, enabling the researchers to assist users with software problems and to collaborate with other researchers. From January 1, 2000, through December 15, 2001, the researchers received 71 requests for assistance, 19 of which included data files. None of the data files had any names or patient identifiers. Of these 19, in 8 cases the researchers sent back modified output files. In two of these eight cases, the researchers could see results of research interest; one of them concerned human data. In 2 of the 19 cases, the researchers sent back modified input files; in one such case, they established a collaboration with the originator of the files. In sum, most requests come under the heading of customer service, with no research contents. A few, however, do lead to research results or collaborations, for which ethics committee oversight is required. Over the three-year time frame of this protocol, the researchers anticipate receiving data on a maximum of 10,000 individuals. They have modified their software documentation to explicitly instruct users to make sure the data files they send have no names. Should they receive files with names, they will delete the files and ask the originator to resubmit them with names encoded. Users submit data through unencrypted e-mail. The data are stored in password-protected computers at the National Institutes of Health.
